Forams confirmed

Show ten foram experts a foram and chances are, they will come up with five different names for it. We had seen it when we did “theElphidium game”. And that tells you taxonomy is partly a personal choice; as long as you know why you call something a certain species, and you are consistent, you do the best you can. And part of taxonomy is also learning what other people might call something. If you find Haynesina germanica where someone else only finds Nonion depressulus, it is worthwhile to realise that might not be an ecological change, but just a different moniker. 

Does that mean you can just do what you want with foraminifera taxonomy? No, of course not. I had stared at my Norfolk forams for months, tried to identify them, looked up what other people had made of them, learned to recognise the Cretaceous forms that had ended up in my much younger sediments, and had come up with quite a good guess of what species I had in there. But it’s hard to be sure; I have many Elphidiums in there, for example, and there just are so many of them. The online World Register of Marine Species mentions 161 species. And that’s far from exhaustive; I already saw some that were not among those 161. And quite some of these species will be synonyms, but still. No way you have specimens, or descriptions in books, or good pictures, of all those species. At some point you have to just pick one and stick with it. But it helps if someone, who has seen many more of these 161 species (and much more species of non-Elphidiums!) has a look at them. 

So when I had my draft classification I went to one of our proper foraminifera specialists; not a specialist-by-proxy such as me, who just uses them for various applications, but one who studies them for their own sake. I gave him a slide with the forams I had encountered in my samples, and what I thought they were. He promised to have a look at them. 

Then some slightly nervous days passed. What if I had it all wrong? What then? But then he gave me my slide back. And basically, everything was OK. I could finalise my counts and start drawing the graphs. Which I did! With renewed faith in my taxonomy skills. The details in taxonomy remain a personal thing, but these are now built on a stronger framework!

Enigmatic jewellery

Self-made jewellery rules! And I'm not even the only one who produces it. For the first time in a way too long time I managed to have lunch with Neil. I think it's been over a year; I'm not very good at remembering when things happen, but with the aid of my blog I seem to be able to conclude it's really been that long. And one of the topics that can never be avoided is tin. Readers of the blog will be aware of his affection for this metal. And he had been making things like cuff links and broaches of it. With the logo of his law firm on it. And he gave one to me! Very nice. I'll wear it with pride. Maybe it will magically make the time period to our next encounter somewhat shorter than the previous one...

Goodbye Beatrix

There were quite some references to the Dutch queen on Facebook. Would the Dutch know something I didn't know? And then, explicit messages about her abdicating were posted. I decided it was time to check a Dutch online newspaper. And I found out that a speech by the queen would be broadcast at 7PM local time. A speech in which she was expected to announce her abdication. It was 18.40 Dutch time when I saw that.

By 7PM I had Dutch radio streaming live. Of course! I was four years old when our current queen, Beatrix, accepted the throne. I don't remember that at all. For all I care, she has always been our queen! It's strange when things that have been constant for decades suddenly change. And when I refer to historical facts instead of my own perception, I have to conclude we have not had a king in living history. Beatrix's great-grandmother took the throne in 1890. And today, in my humble office, I heard her confirm that on Queen's day 2013, we'll get the first king since then. It did stir something. Would we then also start to celebrate King's Day? We'll find out on April 30th! I hope Beatrix enjoys a well-earned retirement...

Dutch pride

There are some things the Dutch just are good at. Dredging, keeping the sea out, locking their bicycles. Earlier this week I walked into the bicycle parking in the evening, and noticed there were little notes dangling from most of them. From all except mine, to be more precise. One can imagine my curiosity. And when I had done a little dance to make the motion sensor switch the light on, and read one of these notes, I must admit a pang of pride. It warned the owner of the bicycle that it was not adequately locked, and was vulnerable to theft. All but mine! And yes, of course, maybe mine had had one and it had fallen off, but I don't think so. I think I may have been the only Dutchie of all the people who had parked there...

PS All this happened again - that confirms my bike just doesn't get these notes!

Luna

The title of this posting should have been different. We were supposed to go to a mine nobody had been in for decades. It had been capped. The landowner, though, had decided to take the cap off, and ask us to have a look what was inside. Of course we jumped at the opportunity! Uncharted territory is quite special. Even though you shouldn't have your hopes up too high: you might hit a collapse after mere feet and not be able to get any further. But we took the chance.

I was already approaching the regional road when suddenly it dawned on me I had forgotten my caving suit. Shit! And this would only be the beginning. I turned back, very displeased with myself, got the suit, and then drove west once again, a bit faster I otherwise might have done. That didn't stop people from overtaking me; very close to the meeting point, a black car passed me, with a lady in it who waved frantically at me. It turned out to be Lionel's girlfriend; she had made her debut in the caving club when I was in the Netherlands, and today she intended to bike around while we explored this new mine. I was glad to meet her!

When we reached the services that functioned as our meeting point, some of us decided to wait inside, and have a coffee; some of us are quite infamous for often being late. When the late-comers arrived, those waiting for them outside failed to inform them we were already there, so they waited outside for us while we waited inside for them. Brilliant! When that was resolved we went to the actual mine, or rather; we tried; we lost the only person who knew where it was, and he doesn't have a mobile phone. By some magic we found it anyway, and by more magic we managed to not get stuck on the muddy track with our two-wheel drives. We had a look at the hole; it looked promising, though wet! The big heavy tractor that had been used to lift off the cap was still there, so we could easily rig from it. I decided to change.

Then I gathered my stuff and wanted to lock the car. the keys, where were the keys? I'm always afraid to lock the keys inside the car, so this time I had stuck them underneath my knee pads, so that couldn't happen. But they weren't there anymore. They must have fallen out. But there were no keys to be seen on the few square metres of ground I'd walked on!

I looked and looked. Felt through the mud of the track, several times. Searched my tackle bag. Several times. And my other bags. And all my pockets. Everything! In the meantime others had rigged the hole, and gone down. I decided they were really gone; we had better just go underground, and phone the AA once we were out. But when I got to the hole, Mark was already coming out; it didn't go! There was a passage from the shaft, but it only lead some ten metres. A bit disappointing. But what can one do...

 

Mark emerges from the new shaft

Upon hearing of my key ordeal, someone suggested I should strip. These keys must be somewhere! And that was reasonable advice. So I started with taking my harness off. And what did I immediately see? My keys! They were draped elegantly over the sling I have hanging from the back of the harness, to hang my bag from when moving along a rope. (You don't want to have a bag on your back; it will pull you backwards. A bag hanging underneath you will keep your body vertical.) I believe that when I knelt to tie my shoe laces, the sling had ended up near my knee, and hooked behind the keys. And they had stayed there, all that time I was looking. I felt stupid, but I was glad I had them again! This also meant I could join the alternative trip; there was a mine nearby I had never visited. This was Luna.

We drove to the other venue, and kitted up again. Including Lionel's girlfriend; she hadn't been up for an unknown trip with serious SRT, but Luna was known and not so demanding. Though when we tried to get to the entrance things got rather challenging after all! Nasty climbs down, involving blind jumping; not my favourite. And then we saw Mark appear from somewhere else; he knew the hard-to-find but easy-to-negotiate way. Dear. It really was that kind of day. But from then on all would go well; we got to the entrance, reached a small internal shaft, rigged it, went down, had a scurry around, marvelled at the very irregular maze of tunnels, had a drink, and then went back. We had a great time!

When we got out the sky was already turning pink

When we were out I was pleased to see Lionel's girlfriend had enjoyed herself. Good! We'll see her next week! It's always nice if you see people be infected withe the caving bug. And without further issues with keys or suits or misunderstandings we went to the pub for a nice after mine pint. And then went home. Maybe not what we had hoped; it would have been nice to explore a new mine, but this was a good day too! In spite of all its silly mishaps!

For both lab and car

Driving is boring! And microscope work can be too! And boring activities are best alleviated with music or other entertaining sounds. These were in short supply; my car radio had stopped working years ago, and a few months ago the DAB radio in the lab decided to only work by high exception. We still have an old analogue radio that's just willing to play some Radio Devon (with some white noise for free) if you ask nicely. Not ideal! And in both venues, wearing earplugs has distinct disadvantages. So I decided to kill two birds with one stone and by a DAB radio of my own. And not just any; one with an iPod docking station. It works on both mains and batteries, so it can come with me into the car, into the lab, and wherever else I want to listen to music. Or BBC4. Or my iPod, if no radio station has anything to my liking, or the signal is bad. And it works well! I already once worked later in the lab than intended, because i couldn't rip myself away from the radio. And in the car it turns out to fit snugly onto the dashboard, and to not start to slide or fall off, even when I do a U-turn! I'm quite happy with it. Bring on the long drives, and the endless forams!

New running routine

It didn't go right the first time around, but I think I now have myself sorted out! Running-wise, that is. I already blogged about my New Year's resolution to get running again, and how that ended in tonsillitis. Not a great start. But I waited until my throat had retrieved its normal proportions and tried again. And now I have developed a stable-looking habit of going for a run before work every second day. It isn't the easiest routine; I'm not a morning person. Especially on the physical front. And it being January, it also is rather cold and dark at the hour I now run. That doesn't help either. Neil already remarked that such difficulties only make it better; I disagree, but I am glad I seem to make it work. It's none too early either; next month I'll be dragging very heavy backpacks over the Norwegian hills! I'll be needing all the fitness I have for doing that!

 

This is what my new style runs look like: with lots of (hi viz) clothes on, in the dark!

Devonport Park is better for running through when the sun sets, but well, it could be worse than this!
